I used highways as an example, but it is anywhere federal money is used in your state. But since you say they are 100% funded.. Good for IL to be off the feds grips and 100% self funded.. Not normal.
But when everyone else moves to the compatible system IL will be left in the dust.. Only usable in IL because my guess they will all need to change to a new RFID type frequency common among the passes. My guess your pass will not just so happen to be the one they switch to. If they are like every other money making corporation they will keep up just to keep making money from you using your pass East of the Mississippi.

Hmm, not sure if I've used the ezpass in NY. Guess that makes sense. They just installed the similar invoicing system like Florida's along the PA NJ border. Pretty neat buy not looking good for toll takers..

In Il the toll roads are not federally fund. The toll road is totally funded by the the toll road user through the toll fees on the road. Nor are any state funds used either for the IL toll road. So there is no incentive to make the I-pass or the EZ pass to be able to work on all toll roads in the US. I know for a fact that my I-pass did not work in CO, and OK on theses toll roads, but did work on most of the toll roads east of the Mississippi River.

The toll roads may not be federally funded but the interstates are and that there will be enough incentive to push the states to adopt te ezpass, su pass and whatever pass to work on all roads. No state is free of federal highway funding and that will be the funds withheld if states do not fall in line with mandate.

Use to work for PennDOT. PennDOT and turnpike commission funding are intertwined. Now PennDOT gets some of the turnpikes revenue the last I knew.

Bottom line Feds will most always get what they want by withholding any and all state federal funding.

When last I towed in NY, (which does have EZ Pass), I still needed to go through the "truck" lanes because they did not have axle counters installed in the approach.

Once you pulled up to the toll taker, the operator just keyed in your axles/weight and waived you through (charging your EZ Pass).

Only cars can use the designated EZ Pass lanes in NY for that reason unless there has been a big change recently.

I called EZ Pass and they gave me a blue colored EZ Pass to use while towing. Seem simple enough as long as I remember to switch back the original once done towing. Another thing to add to the check list. Your statement is correct also about the operator making the correction and waving you thtough, a booth worker told me something similar last summer when I asked.

As technology improves, they really won't even need transponders any more. Here in IL I have 3 vehicles registered to a single transponder account but I keep the transponder in the camper as that's what we use when go east. When we use the cars in IL, without the transponder, the camera's see the plate and charge us. It also sees whether or not you are towing at each toll lane and charges correctly, never misses, darn it. I'd like to thank the governor who put this system in, once he gets out of prison.

Don't forget to put the one you are not using in the Mylar bag (or wrap in aluminum foil). You might get charged on both ...
